This method attaches one or more rnc.PARA_N
elements to the given parent node.
# - - - N a r r a t i v e . w r i t e N o d e
def writeNode(self, parent):
"""Output self's content as XML.
"""
Normally the content is a sequence of Paragraph instances. In that case, all we need
to do is to call the .writeNode() method
for each of those instances. See Section 19.4, “Paragraph.writeNode(): Write as
XML”.
When the instance's content is only a single para, we
don't need to wrap the output in a para
element, so we bypass the addition of this node and
directly use Section 19.5, “Paragraph.writeContent(): Write the
content of a paragraph”.
#-- 1 --
if len(self._paraList) > 1:
#-- 1.1 --
# [ parent := parent with XML added for each element
# of self._paraList ]
for para in self._paraList:
para.writeNode(parent)
elif len(self._paraList) == 1:
#-- 1.2 --
# [ parent := parent with XML added for the first
# element of self._paraList ]
solePara = self._paraList[0]
solePara.writeContent(parent)
